Audio Connector

3-pin XLR female input

Wiring

Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies

Pin 2: Signal + Pin 3: Signal –

Case: Earth ground and chassis

Input Polarity Switch

Reverses audio input polarity between pins 2 and 3 (subwoofer only)

Input Select Switch⁹

Determines whether the subwoofer receives it source signal from the subwoofer input or satellite inputs (summed)

Gain Knob¹⁰

Adjusts the subwoofer signal from completely attenuated to +10 dB

AC Power Connector

powerCON 20 input with loop output

Satellite Loudspeaker Connectors¹¹

Two XLR female inputs; Two Phoenix 5-pin male or EN3 5-pin female outputs (two pins for DC power, three pins for balanced audio)

LED

Displays loudspeaker status
